FIELD OF THE DISCLOSURE

The present disclosure generally relates to methods and supplements for improving fertility in a subject. In some embodiments, a nutritional supplement may be administered to a subject to increase levels of growth hormone (hGH) in the subject, thereby increasing fertility in the subject.

BACKGROUND

The primary biological function of human growth hormone (hGH) includes stimulating growth, cell repair, and regeneration. Once the primary growth period of adolescence concludes, the primary function of hGH in adulthood becomes that of cell regeneration and repair, helping regenerate skin, bones, heart, lungs, liver, and kidneys to their optimal, youthful cell levels. As is the case with many of our other hormones or their precursors, such as testosterone, estrogen, progesterone, DHEA, and melatonin, hGH levels decline with age. Therapeutically, many of these hormones can be replaced to offset some of the effects of aging such as menopausal symptoms in women or erectile dysfunction in men. Additionally, hGH and testosterone affect sterility and fertility in animals, including human beings.

The human body, like every other living entity, works on daily, or circadian, as well as monthly and annual rhythms. Daily growth hormone secretion diminishes with age with roughly half the levels at age 40 that we had when we were 20, and about one-third of those youthful levels at age 60. In some 60-year-olds, the levels are as low as 25% of the hGH levels in a 20-year-old. Symptoms of aging include loss of muscle, increase of fat, decreased physical mobility, decreased energy levels, and as a result, diminished socialization, diminished healing ability, and an increased risk of cardiovascular disease and decreased life expectancy. Low hGH levels are associated with the aging process and early onset of disease. For example, Rosen and Bengtsson noted an increased death rate from cardiovascular disease in hGH deficient patients. (Rosen, T., Bengtsson, B. A., Lancet 336 (1990): 285-2880)

Low hGH has been shown to decrease fertility in humans. See, e.g., Homburg, R., A. Singh, et al. (2012), “The re-growth of growth hormone in fertility treatment: a critical review.” Hum Fertil (Camb) 15(4): 190-193; Giampietro, A., D. Milardi, et al. (2009), “The effect of treatment with growth hormone on fertility outcome in eugonadal women with growth hormone deficiency: report of four cases and review of the literature.” Fertil Steril 91(3): 930 e937-911; Kalra, S., B. Kalra, et al. (2008), Growth hormone improves semen volume, sperm count and motility in men with idopathic normogonadotropic infertility. 10th European Congress of Endocrinology. Berlin, Germany, Endocrine Abstracts. 16: P613; Karaca, Z. and F. Kelestimur (2011), “Pregnancy and other pituitary disorders (including hGH deficiency).” Best Pract Res Clin Endocrinol Metab 25(6): 897-910; Magon, N., S. Singh, et al. (2011), “Growth hormone in male infertility.” Indian J Endocrinol Metab 15 Suppl 3: S248-249; and Sakai, S., T. Wakasugi, et al. (2011), “Successful pregnancy and delivery in a patient with adult hGH deficiency: role of hGH replacement therapy.” Endocr J 58(1): 65-68, the contents of each of which are incorporated herein by reference.

Until recently, hGH was available only in expensive injectable forms, and benefits from the restoration of hGH levels available only to those with the ability to pay. Most recently substances that can trigger the release of human growth hormone from an individual's own anterior pituitary gland have become available. These are generically referred to as secretagogues. Secretagogues have the ability to restore hGH levels, potentially to the levels found in youth. See, e.g., “Grow Young With hGH” by Dr. Ronald Klatz, President of the American Academy of Anti-Aging, published in 1997 by Harper Collins.

HGH-deficient adults have marked reductions in lean body mass, and within months of hGH treatment, gains in lean body mass, skin thickness, and muscle mass are observed. (Cuneo R C et al. J Appl Physiol 1991; 70:695-700; Cuneo R C et al. J Appl Physiol 1991; 70:688-694; Rudman D et al. N Engl J Med 1969; 280:1434-1438)

It is well-established that intravenous (IV) administration of some amino acids results in significant hGH secretion. Intravenous infusion of 183 mg of arginine/kg body weight in females increased hGH levels >20-fold, and 30 g of arginine elevated serum hGH levels 8.6 fold in males. (Merimee T J et al. N Engl J Med 1969; 280:1434-1438; Alba-Roth J et al. J Clin Endocrinol Metab 1988; 67:1186-1189) Other amino acids, such as methionine, phenylalanine, lysine, histidine, and ornithine, have also led to marked increases in hGH. (Alba-Roth, Muller, Schopohl, & von Werder, 1988; Chromiak & Antonio, 2002; Gourmelen, M., M. Donnadieu, et al. (1972) Ann Endocrinol (Paris) 33(5): 526-528)

Given the difficulties in IV administration of amino acids for widespread use, interest in elucidating the hGH response to oral amino acid supplements prompted testing of such supplements containing mainly arginine, lysine, and ornithine at varying amounts. Yet the pronounced variability in results among these studies makes clear the complexities involved in the design of an effective supplement for supporting hGH levels in the general public. (Suminski R R et al. Int J Sport Nutr 1997; 7:48-60; Lambert M I et al. Int J Sport Nutr 1993; 3:298-305; Corpas E et al. J Gerontol 1993; 48:M128-M133; Isidori A et al. Curr Med Res Opin 1981; 7:475-481; Fogelholm G M et al. Int J Sport Nutr 1993; 3:290-297; Chromiak J A, Antonio J. Nutrition 2002 July; 18(7-8):657-61)

Serum hGH levels differ in relation to various factors including age, gender, hormone status, and BMI. (Iranmanesh, Lizarralde, & Veldhuis, 1991); (Chowen, Frago, & Argente, 2004) Growth hormone has been shown to be important in multiple stages of pregnancy including early antral follicle recruitment, subsequent follicular growth, and oocyte maturation. Moreover, administration of growth hormone during the ovarian stimulation phase of in vitro fertilization (IVF) cycles has been shown to increase the probability of clinical pregnancy.

BRIEF SUMMARY OF THE DISCLOSURE

Described herein are nutritional supplements and methods for using the same. In embodiments, the nutritional supplement may be an amino acid secretagogue composition, which, when administered orally, stimulates the pituitary gland of a subject to release growth hormone (e.g., hGH), and results in the promotion or maintenance of fertility.

Some embodiments include an oral nutritional supplement that comprises, for example and without limitation: L-arginine, oxo-proline, L-lysine, and cysteine. Particular examples include an oral nutritional supplement that consists essentially of L-arginine hydrochloride, oxo-proline, L-lysine hydrochloride, N-acetyl-L-cysteine, L-glutamine, and schizonepeta powder.

Certain embodiments herein include an oral nutritional supplement dosage form that consists of 0.86 mmol L-arginine; 1.32 mmol oxo-proline; 2.05 mmol L-lysine; 1.53 μmol N-acetyl L-cysteine; 1.71 μmol L-glutamine; and 125 μg schizonepeta (aerial parts) powder. This oral nutritional supplement is referred to herein as “SeroVital®.” SeroVital® may be orally administered in an amount of, for example, 2.9 grams (i.e., 4 unit dosage forms) to a human being, so as to stimulate the release of hGH and/or increase testosterone levels in the human being. The nutritional supplement may be administered on a regular basis, such as a weekly or monthly intake at a dosage tailored to the subject's needs; i.e., the nutritional supplement may be administered regularly as multiples (1×, 2×, etc.) of the structural units (pills, tablets, capsules, etc.) in accordance with the needs of the subject.

Some embodiments include a method for increasing growth hormone (e.g., hGH) and therefore increasing fertility in a subject (e.g., a human subject) that comprises administering (e.g., orally) a nutritional supplement to a subject to improve one or more objective health metrics, including for example and without limitation: increasing or enhancing pregnancy and live birth rate; increasing lean body mass; reducing obesity, adipose tissue mass, and anxiety; supporting weight loss; decreasing appetite and atrophic processes in skeletal muscle, liver, kidney, spleen, skin, and bone; and improving at least one of energy, endurance, sleep, metabolism, heart rate, blood pressure, cardiovascular health, sympathetic nervous activity, thyroid response, glucose utilization, mental/cognitive function, reaction time, bone density, hair health and appearance, nail health and appearance, skin health and appearance, libido, and at least one androgen-mediated condition(s).

DETAILED DESCRIPTION

The determination of an effective and safe oral functional blend that stimulates hGH secretion in the general population is important, since athletes, entertainers, and now the general public seek effective hGH support supplements and understand hGH to have rejuvenating properties. Indeed, once partial to athletes and entertainers, the desire for effective supplements to provoke hGH increases now extends to the general public. Not only do they have a goal of building lean tissue and reducing fat, but also of improving/increasing fertility and providing other rejuvenating qualities that hGH is understood to provide. However, the literature on oral amino acids for use in stimulating hGH does not contain clear evidence for an optimized oral amino acid-containing blend able to stimulate hGH in the general public, including both men and women of a wide age range.

Therapeutic use of hGH has been used for improving pregnancy outcomes. Indeed, growth hormone has been shown to be important in multiple stages of pregnancy including early antral follicle recruitment, subsequent follicular growth, and oocyte maturation, and administration of growth hormone during the ovarian stimulation phase of in vitro fertilization (IVF) cycles has been shown to increase the probability of clinical pregnancy.

Embodiments herein provide a nutritional supplement for elevating growth hormone (e.g., hGH) and subsequently improving fertility, pregnancy, and live birth rate outcomes. Particular embodiments provide an amino acid-containing composition that is well tolerated, and may have the result of increasing or elevating hGH release in those individuals whose hGH release rates have slowed as a function of increasing age, or that have normal hGH levels but desire higher hGH levels. The compositions of the present disclosure also result in increasing or enhancing fertility. There is a need for a nutritional supplement that efficiently and demonstrably enhances the production and effects of natural human growth hormone and fertility outcomes in individuals of the general population.

Some embodiments herein provide a nutritional supplement for use by a human being. In particular embodiments, the nutritional supplement is an amino acid secretagogue composition, which, when administered orally, may stimulate the pituitary gland to produce hGH, and may jointly promote or maintain fertility.

Increased production of hGH may result in enhancement of fertility; inhibition of insulin depression; inhibition of hyperglycemia and increase in insulin effectiveness; enhancement of fat conversion; lowering of cholesterol; and/or normalization of lipid balance. In examples, a supplement herein may function as a dietary supplement by assisting the body's own ability to secrete hGH naturally, and in a manner which is safe and effective. Such a supplement may provide growth hormone therapy in a more affordable manner than existing compositions and methods, for example, injectable compositions.

Particular embodiments herein include an oral nutritional supplement that comprises L-lysine, L-arginine, oxo-proline, and one of cysteine and glutamine. In some examples, a supplement herein may comprise both cysteine and glutamine and/or schizonepeta powder. In particular examples, a functional dosage includes the L-arginine at a level between about 0.1-6 mmol and the oxo-proline between about 0.1-8 mmol, and/or the L-lysine in an amount between about 0.1-12 mmol. In particular examples, the cysteine and/or glutamine may be contained at a level between about 0.001-6 mmol.

Cysteine may be present in a supplement according to particular embodiments as n-acetyl L-cysteine, and the glutamine may be L-glutamine. Amino acids in a nutritional supplement herein may be delivered as non-toxic salts thereof, effective complexes thereof, stable chelates thereof, active esters thereof, functional derivatives thereof, and mixtures thereof which are effective to increase hGH levels in a subject from the general population.

Particular embodiments herein include an oral nutritional supplement that consists essentially of L-lysine (e.g., L-lysine HCl), L-arginine (e.g., L-arginine HCl), oxo-proline, N-acetyl-L-cysteine, L-glutamine, and schizonepeta (aerial parts) powder. In particular examples, a functional dosage includes L-arginine at a level between about 0.1-6 mmol and oxo-proline between about 0.1-8 mmol, and/or L-lysine in an amount between about 0.1-12 mmol. n-acetyl L-cysteine and/or L-glutamine may be comprised in some exemplary supplements at a level between about 0.001-6 mmol. In particular examples, a functional dosage includes L-arginine at a level between about 2.5-4.5 mmol and oxo-proline between about 4-6 mmol, and/or L-lysine in an amount between about 7-9 mmol. N-acetyl L-cysteine and/or L-glutamine may be comprised in some exemplary supplements at a level between about 0.001-0.5 mmol.

Certain embodiments herein include an oral nutritional supplement dosage form that consists of 0.86 mmol L-arginine; 1.32 mmol oxo-proline; 2.05 mmol L-lysine; 1.53 μmol N-acetyl L-cysteine; 1.71 μmol L-glutamine; and 125 μg schizonepeta (aerial parts) powder (SeroVital®). Thus, an oral nutritional supplement dosage form may consist of 181.38 mg L-arginine HCl; 170.93 mg L-pyroglutamic acid; 374.83 mg L-lysine HCl; 0.25 mg N-acetyl L-cysteine USP; 0.25 mg L-glutamine; and 0.125 mg schizonepeta (aerial parts) powder, for example, in a capsule. In some examples, the oral nutritional supplement may be administered to a human being by orally administering four such dosage forms (i.e., 725.50 mg L-arginine HCl; 683.70 mg L-pyroglutamic acid; 1499.30 mg L-lysine HCl; 1.00 mg N-acetyl L-cysteine USP; 1.00 mg L-glutamine; and 0.50 mg schizonepeta (aerial parts) powder).

Some embodiments herein provide a method for increasing or enhancing fertility in humans, and increasing human growth hormone in humans that comprises orally administering a nutritional supplement for elevating growth hormone release to a healthy human being. As used herein, a “healthy human being” refers to a human being having any age-related decline in hGH, excluding any physiological deficiency that is not age related. Particular embodiments include oral administration of a nutritional supplement for elevating growth hormone release to a human that is at least 30 years old.

Other embodiments herein provide a method for increasing or enhancing fertility in humans, and increasing human growth hormone in humans that comprises orally administering a nutritional supplement for elevating growth hormone release to a human being that has a deficiency of hGH, or any condition resulting in low fertility or infertility, such as humans having pituitary disorders, idiopathic normogonadotropic infertility, and/or low hGH.

A nutritional supplement for elevating growth hormone release may be orally administered to a human being to improve health, including by: increasing lean body mass; reducing obesity, adipose tissue mass, and anxiety; supporting weight loss; decreasing appetite and atrophic processes in skeletal muscle, liver, kidney, spleen, skin, and bone; and improving energy, endurance, sleep, metabolism, heart rate, blood pressure, cardiovascular health, sympathetic nervous activity, thyroid response, glucose utilization, mental/cognitive function, reaction time, bone density, hair health and appearance, nail health and appearance, skin health and appearance, and libido.

In certain examples, oral administration of a nutritional supplement for elevating growth hormone release may improve fertility. Oral administration of a nutritional supplement for elevating growth hormone release may also improve wound healing, provide anti-aging skin properties, reduce wrinkles, dark spots, discolorations, dullness, sagging, laxity, and thinning, and may further improve texture, luminosity, “lift,” tone, radiance, smoothness, uniformity, and youthful look of skin.

A nutritional supplement for elevating growth hormone release may be orally administered to a human being to improve health by affecting one or more condition(s) and/or disease(s) that depend upon androgen activity. Such conditions and diseases include, for example and without limitation: low fertility; infertility; maintenance of fertility; maintenance of muscle strength and function; reversal or prevention of frailty or age-related functional decline (ARFD) in the elderly (e.g., sarcopenia); remediation of age-related decreased testosterone levels in men; treatment of male menopause; treatment of hypogonadism; male hormone replacement; treatment of male and female sexual dysfunction (e.g., erectile dysfunction, decreased sex drive, sexual well-being, decreased libido); male and female contraception; hair loss; Reaven's Syndrome; enhancement of bone and muscle performance/strength; treatment of catabolic side effects of glucocorticoids; prevention and/or treatment of reduced bone mass, density, and/or growth (e.g., osteoporosis and osteopenia); treatment of chronic fatigue syndrome (CFS); chronic myalgia; treatment of acute fatigue syndrome and muscle loss following elective surgery; acceleration of wound healing; acceleration of bone fracture repair; prevention of post-surgical adhesion formation; acceleration of tooth repair or growth; maintenance of sensory function (e.g., hearing, sight, olfaction, and taste); treatment of periodontal disease; treatment of wasting secondary to fractures and wasting in connection with, for example, chronic obstructive pulmonary disease (COPD), chronic liver disease, AIDS, weightlessness, cancer cachexia, burn and trauma recovery, chronic catabolic state, eating disorders, and chemotherapy; treatment of cardiomyopathy; treatment of thrombocytopenia; treatment of one or more symptoms of Crohn's disease; treatment of short bowel syndrome; treatment of irritable bowel syndrome; treatment of inflammatory bowel disease; treatment of ulcerative colitis; treatment of complications associated with transplantation; treatment of physiological short stature; treatment of obesity and growth retardation associated with obesity; treatment of anorexia (e.g., associated with cachexia or ging); treatment of hypercortisolism and Cushing's syndrome; treatment of Paget's disease; treatment of osteoarthritis; induction of pulsatile growth hormone release; treatment of osteochondrodysplasias; treatment of depression, nervousness, irritability, and stress; treatment of reduced mental energy and low self-esteem (e.g., motivation/assertiveness); improvement of cognitive function (e.g., treatment of dementia, including Alzheimer's disease and short-term memory loss); treatment of catabolism in connection with pulmonary dysfunction and ventilator dependency; treatment of cardiac dysfunction (e.g., associated with valvular disease, myocardial infarction, cardiac hypertrophy or congestive heart failure); lowering of blood pressure; protection against ventricular dysfunction or prevention of reperfusion events; treatment of adults in chronic dialysis; reversal or slowing of the catabolic state of aging; attenuation or reversal of protein catabolic responses following trauma (e.g., reversal of the catabolic state associated with surgery, congestive heart failure, cardiac myopathy, burns, cancer, COPD, etc.); reduction of cachexia and protein loss due to chronic illness such as cancer or AIDS; treatment of hyperinsulinemia, including nesidioblastosis; treatment of immunosuppressed patients; treatment of wasting in connection with multiple sclerosis or other neuro-degenerative disorders; promotion of myelin repair; maintenance of skin thickness; treatment of metabolic homeostasis and renal homeostasis (e.g., in the frail elderly); stimulation of osteoblasts, bone remodeling, and cartilage growth; regulation of food intake; treatment of insulin resistance, including NIDDM; treatment of insulin resistance in the heart; improvement of sleep quality and correction of the relative hyposomatotropism of senescence due to high increase in REM sleep and a decrease in REM latency; treatment of hypothermia; treatment of congestive heart failure; treatment of lipodystrophy; treatment of muscular atrophy; treatment of musculoskeletal impairment; improvement of the overall pulmonary function; treatment of sleep disorders; treatment of the catabolic state of prolonged critical illness; treatment of hirsutism, acne, seborrhea, androgenic alopecia, anemia, hyperpilosity, benign prostate hypertrophy, adenomas, and neoplasias of the prostate (e.g., advanced metastatic prostate cancer) and malignant tumor cells including the androgen receptor, such as is the case for breast, brain, skin, ovarian, bladder, lymphatic, liver, and kidney cancers; treatment of cancers of the skin, pancreas, endometrium, lung and colon; osteosarcoma; hypercalcemia of malignancy; metastatic bone disease; treatment of spermatogenesis, endometriosis, and polycystic ovary syndrome; counteracting preeclampsia, eclampsia of pregnancy and preterm labor; treatment of premenstrual syndrome; and treatment of vaginal dryness.

A nutritional supplement for increasing fertility and/or elevating growth hormone release may be used in combination with other hormone and/or steroid modulating supplements to enhance the effect of the nutritional supplements disclosed herein.

In accordance with the “consist essentially of” and “consisting essentially of” language herein, a nutritional supplement for elevating growth hormone release in some embodiments is essentially limited to the aforementioned ingredients, and does not include any additional active ingredients intended to add nutritional content (e.g., vitamins, minerals, etc.), but may include additional ingredients not intended to add nutritional content, for example, ingredients intended to fulfill a non-nutritional purpose (e.g., coloring, fillers, flavoring, an ingredient for maintaining the structural form, etc.).

Each ingredient of a nutritional supplement for increasing fertility and/orelevating growth hormone release may be prepared in accordance with any method known to one of ordinary skill in the art. Alternatively, each ingredient may be obtained in a fully prepared form from a commercially available source.

A nutritional supplement for increasing fertility and/or elevating growth hormone release may be in any suitable oral administration form, including but not limited to: a chewable form, a liquid form, a spray form, a capsule form, a suppository form, dissolvable wafer, and a powder form. In some embodiments, a dosage form of the nutritional supplement may be present in an amount of about 2.9 grams.

Irrespective of the structural form of the nutritional supplement for increasing fertility and/or elevating growth hormone release, the ingredients of the nutritional supplement may be distributed homogeneously or non-homogeneously within the nutritional supplement.

A nutritional supplement for increasing fertility and/or elevating growth hormone release may be ingested on a regular basis, such as a daily or weekly intake at a dosage tailored to an individual's needs, i.e., the nutritional supplement is to be taken regularly as multiples (1×, 2×, etc.) of the dosage form (e.g., pills, tablets, capsules, etc.) in accordance with the needs of the individual. For example, a senior citizen leading a sedentary life is likely to need higher daily doses than does a young person engaged in regular strenuous exercise (e.g., a weight lifter).

Alternatively, the nutritional supplement for increasing fertility and/or elevating growth hormone release may be ingested on an as-needed basis at a dosage tailored to the individual's needs. Medical or nutritional counseling may be beneficial for arriving at a desirable or optimal dosage tailored to the individual's needs. The nutritional supplement may be administered, for example, from one to three times daily, or, by way of further example, the supplement may be administered every other day or once a week. In particular embodiments, the nutritional supplement may be administered on an empty stomach.

In certain embodiments, a nutritional supplement for increasing fertility and/or elevating growth hormone release comprises a particular combination of types of amino acids, mass ranges, and specific formulations that have been selected to be synergistically balanced and of adequate quantity to achieve a desired physiological effect, e.g., growth hormone release and increased fertility. Improper combinations of the same amino acids may be ineffective. The component amino acids may be synergistic in the sense that several of them, when combined together, synergistically stimulate the release of human growth hormone, leading to enhanced fertility. The combination of amino acids in particular embodiments was also chosen to reduce or inhibit chemical combination or reaction between the component amino acids.

EXAMPLES Example 1: Effect of an Oral Nutritional Supplement Single Dose on hGH Levels

The short-term effects of a single oral nutritional supplement on hGH levels 2 hours post ingestion was studied in 16 healthy subjects [12 males, four females; nine Caucasian, six African American, one other; mean age=32±14 years; body mass index=26.4±5.0 ranging from 19.1 to 36.8 kg/m²]. Each subject reported to the Inpatient Unit on two occasions one week apart. After an overnight fast, subjects had an IV line placed and baseline bloods samples were drawn at −30, −15,and 0 minutes.

Subjects were then asked to swallow the capsules of supplement (SeroVital®) or an identical looking placebo. SeroVital® is a 2.9 g/dose blend of L-lysine HCl, L-arginine HCL, oxo-proline, N-acetyl-L-cysteine, L-glutamine, and schizonepeta (aerial parts) powder. Blood was drawn at 15, 30, 60, 90, and 120 minutes for assay. Human GH was measured at each time point using the Siemens Immulite™ 2000 (intra-assay CV was 3.72%, inter-assay CV was 5.70%, and the detection limit for hGH was 0.05 ng/mL. The −15 and 120 minute time points were additionally assayed for triiodothyronine (T3) as informative for mechanistic investigations.

The mean growth hormone increased 682% after the supplement from 0.17 at baseline to 1.33 ng/mL at 120 minutes, compared to a mean decrease of 52% after the placebo from 0.93 to 0.45 ng/mL. FIG. 1.

The mean change in hGH levels from baseline to 120 minutes (hGH at 120 minutes minus hGH at 0 minutes), was 1.15 (95% CI: 0.17, 2.14) ng/mL after the supplement, versus −0.48 (−1.47, 0.50) ng/mL after the placebo, demonstrating a statistically significant differential effect (P=0.01). After the supplement, the mean AUC for hGH across 120 minutes was 20.43 (95% CI: 19.90, 20.95) ng/mL/min which was significantly higher (P=0.04) than placebo at 19.67 (18.74, 20.59) ng/mL/min. Overall, 120 minutes after taking the supplement, hGH levels were significantly higher in absolute levels or by AUC.

As daily circadian levels of T3 naturally decrease during the morning hours, at which the current trial was scheduled, it was not surprising that placebo levels between the −15 and 120 minute time points decreased by −6.10 ng/dL (106 to 100 ng/dL, P=0.01). In contrast, the SeroVital® group exhibited a deceased reduction in T3 by nearly one-half over the same time course, −3.3 ng/dL (101-97.3 ng/dL, NS), which was not a significant reduction compared to baseline, as was the reduction in the placebo group. These results affirm that somatostatin inhibition plays a mechanistic role in the ability of SeroVital® to induce significant increases in serum hGH levels in human subjects.

At 120 minutes, hGH concentrations were two-fold higher in women (2.3±1.1 ng/mL, n=4) than in men (1.0±0.4 ng/mL, n=12, although the study was not adequately powered for these comparisons. Nevertheless, these findings support an enhanced effect of the SeroVital® supplement in women.

An eight-fold increase was observed, equivalent to 682%, in hGH levels 120 minutes after a single oral supplement of SeroVital®. The study had a broad range of ages and BMIs and included both genders. An additional advantage of the present study over previous hGH evaluations is that it contained a placebo control group and was randomized and double-blinded.

These findings demonstrate that a specialized low-dose amino acid supplement can significantly increase short-term hGH levels. Future studies will examine whether such increases in hGH with oral amino acid supplementation increase fat-free mass and strength. This indeed may be the case, since elderly subjects administered oral hGH secretagogues for six and 12 months have sustained increases in lean body mass and improved physical function.

The absolute magnitudes of these results are somewhat difficult to directly correlate among past studies, as commercial hGH assays use different antibodies to target specific hGH epitopes. Therefore, different antibodies and assays are less likely to recognize some specific isoforms and fragments of the hGH molecule. This results in variability of the normal range of the hGH measurements in different assays. Indeed, the same hGH sample measured using different assays can vary two- to three-fold, limiting the ability to compare actual hGH levels across studies. Nevertheless, the mean levels of hGH reached after the subcutaneous injection of 0.06 IU of hGH in the treatment of hGH deficient subjects was 0.4 ng/mL, a value that was clearly in the range of values seen in our study with oral amino acids.

Findings obtained from a randomized, blinded, placebo-controlled study strengthen the evidence that oral administration of amino acids, when compounded properly, can increase hGH serum levels, wherein SeroVital® administration showed an eight-fold increase, equivalent to a 682% increase in hGH levels, 120 minutes after a single oral dose. In addition, we elucidate some mechanistic details for these significant hGH increases as through somatostatin inhibition, supported by our results on the 120 minute results on T3 levels in the same subjects.

Example 2: Effect of an Oral Nutritional Supplement on Fertility

The effects of an oral nutritional supplement on fertility were studied in a group of healthy human subjects. Subjects were asked to swallow capsules of SeroVital®.

Case 1: A 27-year-old woman was admitted to St. Mark's Center for Women's Health for a physical examination with complaints of irregular menses and secondary infertility. Six years previously, she had given birth to her first child. The pregnancy was uneventful with spontaneous labor at 38 weeks. She underwent cesarean section for delivery after failure to progress in labor, and gave birth to a healthy baby. The subject was unable to breastfeed because she did not have sufficient milk production.

Following the birth of her first child, she had experienced weight gain and difficulty losing weight. Her menstrual periods were light and infrequent, numbering approximately two per year with each lasting approximately three days. She and her partner failed to conceive a pregnancy over a six-year period while actively attempting to get pregnant for the last four years.

Upon examination, clinical results were consistent with Polycystic Ovary Syndrome (PCOS), and a uterine ultrasound was performed. Ultrasound confirmed polycystic ovaries and PCOS diagnosis. The patient elected a conservative mode of management by engaging in a targeted diet and exercise program for weight loss. However, she was only able to lose a marginal amount of weight and experienced no changes in menstrual cycles.

After approximately a year and a half of attempting weight loss as the only mode of management, the subject started daily supplementation with SeroVital® (2.9 g/day). After the first two months of SeroVital® intake, she had a menstrual period. After one more month of supplementation, she had another menstrual period. After one more month of supplementation for a total of four months of supplementation, she confirmed pregnancy. She discontinued SeroVital® supplementation after pregnancy was confirmed.

Her second pregnancy proceeded to term without complications and the patient gave birth to a healthy baby boy weighing 10 lbs 6 oz, length 21½ inches.

Case 2: A 33-year-old woman, BMI 37.2, was referred to a reproductive center on Aug. 15, 2013 for secondary infertility and recurrent pregnancy loss. Medical impression included SAB×2 (1 with prior partner); SVD×1; ovulatory dysfunction; menses every 2-3 months; moderate dysmenorrhea; minimal endometriosis. [Male factors showed normal semen analysis].

History: In May of 2001 she experienced an SAB (miscarriage). In January of 2009, she gave birth to a healthy daughter (preeclampsia, on bedrest from 29 weeks), having conceived after a second cycle of Clomid. In January of 2012, she experienced a second SAB (bleeding×2 weeks, serum HCG low and then went down, no sac seen on ultrasound, biochemical).

In August of 2013, the patient had her initial consult and initiated treatment:

Case 3: A 29-year-old woman, 156 cm tall, weighing 49.9 kg (BMI 20.5 kg/m2) desired a pregnancy but had been impacted by endometriosis symptomology since adolescence. She declined surgical and hormonal interventions since her initial diagnosis and managed symptoms of menorrhagia and dysmenorrhea through nutritional and active-lifestyle approaches.

After six months of unprotected intercourse, the subject conceived. She gained 29 kg over the course of pregnancy and suffered from mild nausea, occasional vomiting, and persistent colds. She otherwise had a non-eventful pregnancy and underwent a planned cesarean section for breach presentation at 39 weeks. After delivery, the subject was able to breastfeed for several weeks, after which she did not have sufficient milk production to continue breastfeeding. The subject experienced sharp abdominal pains with any physical motion at the site of cesarean section incision for several months after the delivery and was unable to exercise until the pain subsided. The subject also experienced symptoms of postpartum depression.

Four months following the delivery, the subject began daily supplementation with SeroVital® (2.9 mg/day) and engaged in fitness training. She lost 25 kg and competed in a competitive running event. Nine months after beginning daily supplementation with SeroVital®, the subject conceived an unplanned, second pregnancy from a single unprotected event. She discontinued SeroVital® supplementation after pregnancy was confirmed.

The subject suffered from increased symptoms of illness compared to her first pregnancy including nausea, vomiting on 12 occasions, and persistent colds, but had no other complications. She underwent a planned cesarean section at 42 weeks after spontaneous labor was not reached. The subject breastfed her baby for a period of two weeks. She initiated daily SeroVital® supplementation four weeks after the delivery and two weeks after ceasing breastfeeding.

Three months after restarting daily supplementation with SeroVital®, the subject completed a half-marathon. One month later and four months after restarting SeroVital®, the subject conceived an unplanned, third pregnancy, once again from a single unprotected event. The subject continued SeroVital® supplementation throughout the pregnancy and did not experience symptoms of illness as she did with her previous pregnancies. She underwent a planned cesarean section and tubal ligation at 39 weeks, giving birth to her third healthy baby.

As no other observable changes in diet or medication took place, SeroVital® appears to have heightened her fertility, leading to her timely second and third improbable pregnancies. Ingestion of SeroVital® also appears to have reduced postpartum depressive symptoms after her second and third deliveries, as well as eliminating physical illness symptoms during her third pregnancy. She notes that she did not experience pain with physical motion at the incision site after her second and third cesarean sections as she did with her first, despite the short succession between multiple surgeries.

Example 3: Effect of an Oral Nutritional Supplement on Endurance and Fat Metabolism

To test the effect of the nutritional supplement on endurance and fat metabolism, a double-blind clinical study was conducted involving 12 healthy subjects [seven males, five females; mean age=31±6 years; body mass index=25.7±3.8 ranging from 20.3 to 32.2 kg/m²]. Each subject reported to the Fitness Testing Facility (PEAK, University of Utah College of Health) after an overnight fast. Upon arrival, each subject underwent standard measurements of weight, height, body fat percent (Bod Pod), and resting metabolic rate (RMR, indirect calorimetry). Daily calorie expenditure was estimated based on the additive evaluations of measured RMR, estimated Lifestyle and Activity (defined as the number of calories burned performing daily activities including working, playing, eating, etc.), and estimated Exercise (defined as an estimate of the number of calories burned during exercise based on daily activity level). Following the baseline measurements, subjects then consumed a standard breakfast (Egg McMuffin, 300 calories; 12 g fat; 29 g carbohydrates; 18 g protein). Subjects rested for a further 45 minutes to reach a post-absorptive state, then underwent a Maximal Aerobic Fitness Test of graded exercise, completed on a treadmill. Subjects' oxygen uptake was measured using a metabolic cart, and VO_(2max) was quantified.

Subjects were then provided a two-week supply of a novel supplement SeroVital® (2.9 g/dose blend of L-lysine HCl, L-arginine HCl, oxo-proline, N-acetyl-L-cysteine, L-glutamine, and schizonepeta (aerial parts) powder). The novel SeroVital® increases serum human growth hormone hGH levels by eight times (equivalent to 682%) 120 minutes after a single dose in healthy male and female volunteers. In this study, subjects were instructed to consume one dose of the supplement on an empty stomach, two hours after dinner prior to bedtime, every night for the two-week study duration.

Following the final dose, each subject returned to the PEAK Fitness Testing Facility, University of Utah College of Health, after an overnight fast (without having consumed their last dose of the supplement since the previous night). Upon arrival, each subject underwent the identical test protocols as the baseline test day. The data from the two measurement days were then analyzed. Consistent with the hypothesis that the supplement would improve endurance parameters with its ability to increase in hGH levels, the decision was made to reject the null only if the data supported the one directional alternative consistent with a favorable response to the supplement. Statistical significance was assumed for P≤0.05.

Mean VO_(2max) increased by 6% from 44.9±8.1 at baseline to 47.7±9.2 mL/kg/min (3.69±0.96 to 3.91±1.02 L/min), demonstrating a statistically significant differential effect compared to baseline (P=0.02). After the period of supplementation with SeroVital®, the mean RMR increased by 2.7% from 1687±330 to 1733±288 kcal/day with a statistical trend towards significance compared to baseline (P=0.165). Estimated daily calorie expenditure also increased by 2.7% from 1687±330 to 1733±288 kcal/day with the trend towards significance (P=0.166).

After two weeks of supplementation with the supplement SeroVital® (taken on an empty stomach, two hours after dinner prior to bedtime, every night), both RMR and estimated daily calorie expenditure tended to increase, evidencing the potential of the supplement to impart long-term fat burning effects. Additionally, endurance as measured by VO_(2max) in the post-absorptive state significantly improved with a measured 6% increase. Overall, the SeroVital® supplement was shown to increase parameters of endurance, energy, and vitality.

Example 4: Effect of an Oral Nutritional Supplement on Sleep Improvement

To test the ability of the nutritional supplement to improve sleep, a double-blind clinical study was conducted involving 15 healthy subjects [10 males, five females; mean age=33±7 years]. Each subject completed a baseline Epworth Sleepiness Scale self-report questionnaire and a standardized assay of usual sleep habits. All subjects were deemed to have average sleep parameters within a normal range.

The subjects were then provided a three-week supply of a novel supplement SeroVital® (2.9 g/dose blend of L-lysine HCl, L-arginine HCl, oxo-proline, N-acetyl-L-cysteine, L-glutamine, and schizonepeta (aerial parts) powder). The novel SeroVital® blend increases serum human growth hormone hGH levels by eight times (equivalent to 682%) 120 minutes after a single dose in healthy male and female volunteers.

We investigated sleep patterns with continued use of the supplement when taken on an empty stomach, two hours after dinner prior to bedtime, every night for three weeks. On each trial day, subjects reported 1) time went to bed; 2) time of final awakening; 3) estimated time to fall asleep; 4) time of awakening during sleep/length of time awake. Data was compiled by day for estimated time to fall asleep and length of time awake during sleep in order to assess sleep efficiency. Daily values for each measure were plotted as an average (±S.D.) among the subjects over the time course of the study, and a linear regression was tabulated to assess overall trends over time. All available data was included in the analysis.

Linear regression analysis showed that both estimated time to fall asleep (FIG. 2) and time awake during sleep (FIG. 3) tended to decrease over time with continued use of the supplement over the time course of the study. The time to fall asleep decreased with an average slope of −0.24 min/day, and the time awake during sleep decreased by an average slope of −0.26 min/day. Overall, these results show a trend towards greater sleep efficiency by measurements of both time to fall asleep and time awake during sleep, both with a quantified average decrease of about 0.25 min/day over three weeks with regular nighttime use of the novel SeroVital® supplement (when taken as directed, on an empty stomach, two hours after dinner prior to bedtime).

Example 5: Effect of an Oral Nutritional Supplement on Lean Body Mass and Weight Change

To test the effect of the nutritional supplement on lean body mass and weight change of humans, healthy men and women between the ages of 30 to 80 years are recruited through advertisements. Standardized assessment criteria are used to select subjects at risk for functional decline (e.g., hand grip strength, habitual gait speed, etc.). Additionally, subjects are excluded for diabetes mellitus, use of anticoagulants, seizure disorder, cancer treatment within five years, poorly controlled hypertension, unstable or recent onset angina, myocardial infarction within six months, cognitive impairment, depression, significant limitations of lower extremity function, bradycardia, systolic blood pressure <100 or >170 mm Hg, or orthostatic hypotension. Subjects participating in strength training programs were also excluded.

Subjects are given daily doses of the nutritional supplement for six months at different dosing concentrations of active ingredients, and one group is treated as a placebo group. The study includes a pre-screening assessment, screening and baseline visits, and weekly visits over the planned six months, where weight, body composition, and physical performance (including endurance) are determined, along with hormonal data analysis. Weight, percent lean body mass, and percent fat body mass are chosen as primary measures of body composition at the six-month analysis period.

Example 6: Effect of an Oral Nutritional Supplement on Energy, Bone Density, Skin Thickness, and Mass of Adipose Tissue

To test the effect of the nutritional supplement on energy, bone density, skin thickness, and mass of adipose tissue, healthy men over 60 years old are recruited through advertisements. Standardized assessment criteria are used to select subjects at risk for functional decline (e.g., hand grip strength, habitual gait speed, etc.). Entry criteria include body weight of 90 to 120 percent of the standard for age. Additionally, subjects are excluded for diabetes mellitus, use of anticoagulants, seizure disorder, cancer treatment within five years, poorly controlled hypertension, unstable or recent onset angina, myocardial infarction within six months, cognitive impairment, depression, significant limitations of lower extremity function, bradycardia, systolic blood pressure <100 or >170 mm Hg, or orthostatic hypotension. Subjects participating in strength-training programs were also excluded.

Subjects are given daily doses of the nutritional supplement for six months at different dosing concentrations of active ingredients, and one group is treated as a placebo group. The study includes a pre-screening assessment, screening and baseline visits, and weekly visits over the planned six months, where lean body mass, mass of adipose tissue, skin thickness, and bone density at various skeletal sites are measured. Subjects are also monitored for changes in energy levels throughout the experiment.

Example 7: Effect of an Oral Nutritional Supplement on Anxiety and Sleep

To test the effect of the nutritional supplement on anxiety and sleep, healthy men and women between the ages of 30 to 80 years are recruited through advertisements. Subjects are interviewed by a psychiatrist using the Structured Clinical Interview for DSM-III-R or analogous method. Patients are all drug free. The study focuses on the evaluation of anxiety, sleep patterns, and measurement of basal morning stress hormone levels at various points during the six-month testing period.

Subjects are given daily doses of the nutritional supplement for six months at different dosing concentrations of active ingredients, and one group are treated as a placebo group. The study includes a pre-screening assessment, screening and baseline visits, and weekly visits over the planned six months, where anxiety assessment (e.g., Hamilton Anxiety Rating Scale) and anxiety and stress hormone levels (e.g., cortisol and hGH) are determined, and sleep study analysis are conducted.

Example 8: Effect of an Oral Nutritional Supplement on Testosterone Levels

The effects of an oral nutritional supplement on testosterone levels are studied in a group of healthy human subjects. Subjects are asked to swallow the capsules of SeroVital® or an identical looking placebo.

Blood samples (8-10 mL) are taken from each participant before use, after six days of use, after 12 days of use, and three days after suspending use. Each blood draw is taken in the morning between 9:30 and 10:30 am, at a time when serum oscillations of testosterone is at its minimum daily value. The determination of testosterone in human blood is carried out using commercially available immunochemoluminescence assays. (Topo et al., 2009)

Results on testosterone release show that after using the SeroVital® supplement, serum testosterone levels are increased in a significant number of the subjects taking the supplement. On average, the increase in serum testosterone is statistically significant compared to those of the placebo group over the time course of the study.
